Mr Bush, why only now?

I was reading this article from Irrawaddy by Aung Zaw about his recent encounter with Bush.

No doubt, to many of us, Bush appears as an amicable man who has genuine interest and concern for Burma and its citizens. In fact, when Bush took up the presidency, I was elated to have someone who seemed prepared to take on a tougher stand against the junta. Now, despite Aung Zaw's generous comments about his "seemingly wonderful" encounter with Bush, I can't help but just to say "talk looks really good on the table".

My question to Bush: Mr Bush, why do you have time for Burma only when your term in office is almost over?
